Question

In a Rails 3.1 app, I have a controller returning a set of objects (children) in an index view using this code:

    def index
        @children = Child.all

        @base_class = "children-index"
        @title = "Your Children"

        respond_to do |format|
            format.html # children/index.html.erb
            format.json { render :json => @children }
        end
    end

The index.html.erb view is written like so:

<h1><%= title %></h1>
<ul>
  <%= @children.each do |child| %>
    <li><%= link_to child.fullname, child_path(child) %></li>
  <% end %>
</ul>

For some reason, the JSON response is getting thrown into the HTML response and I cannot determine the reason. None of my other index views are having this issue and their code is very close to the same.

Answer 1

That’s not JSON, that’s inspect output. You’re getting that because each returns @children and you’re using <%= here:

<%= @children.each do |child| %>

You want just this:

<% @children.each do |child| %>
